Luckily for Damon the diapers weren't magicked or anything,so
nothing came of him wearing them.
However after a while Damon came to realize these weren't actually 'diapers" but were called 'briefs' or possibly
'older adult incontinence products'
So Damon checked around and found the package the
briefs had come from,lying near his apartment door where the
Drug Store delivery guy had mistakenly left them,rather then
to their proper owner,the mysterious woman and man whom
Damon had never met but whom he knew lived a few doors
down from him.
Basically Mona,Damons playful puppy dog must have found the
package of briefs and in playing with the package torn it open
with her teeth and scattered briefs around the room.
So Damon gathered up the scattered briefs as best he could and
with Mona wagging her tail and trotting behind her Master
Damon rang on the doorbell of his mysterious neighbour.
They were a elderly couple ,claiming to be a witch and a wizard
who had known Damons ancestor centuries earlier.
A very elderly couple.
So whilst Damon sat in the living room and chatted with the
retired witch
the retired wizard fished out his wand ,waved it at that annoying puppy dog and changed Mona the Puppy into
Mona the Young Woman
just to see if he still had it in him.
